In Search of Dialogicity: A Comparison of Curricular Documents and Classroom Interactions from Finland and Hong Kong
2017
The prevailing consensus is that science teaching should be more student-centered and guide learners towards more phenomenon-based and authentic problem-solving activities. This approach is reflected in educational policies and recently reformed curricula. However, there is limited research on how these frameworks actually manifest in curricula and how to facilitate student-centered pedagogy. In this study, we examine the student-centered features of the curricula of two countries: Finland and Hong Kong. Student-centeredness in the classroom can be assessed using the principles of dialogicity. Dialogic principles underpin student-centeredness, particularly in teacher-orchestrated whole-clas…
Teachers' Attitudes toward Educational Inclusion in Spain: A Systematic Review.
2021
Inclusive education is currently one of the main aspirations of the Spanish educational system and one of the key aspects for its achievement is teachers’ attitudes toward educational inclusion. In recent years, many studies worldwide have analyzed this aspect, but so far, any systematic review has specifically focused on the Spanish educational framework. For this reason, the purpose of this paper is to review the studies published from 2010 to 2019 whose aim was to analyze teachers’ attitudes towards educational inclusion in Spain. After a literature search in four different databases (PsycInfo, ERIC, Dialnet Plus, and Google Scholar), 34 studies were selected and reviewed. The results su…
2021
In recent decades, an essential global aim of the reforms of special education has been the promotion of inclusive education. This article discusses the implementation of reforms with a focus on tiered support systems in the context of Finnish comprehensive school education. Based on earlier literature, legislation, and administrative documents, we provide a background for Finnish education policy and special education reforms. The focus of this article is on the description of parallel reforms targeting the re-structuring of the systems around support for students and funding of education in the 2010s. We discuss the processes leading to these reforms and the reforms themselves. In additio…
“How Real People Really Need Mathematics in the Real World”—Authenticity in Mathematics Education
2018
This paper discusses authenticity from the perspective of mathematics education. Often, school mathematics offers students inauthentic word problems, which don’t show the authentic usefulness of mathematics in real life. In some tasks, authentic aspects are combined with inauthentic ones (e.g., an authentic context, but the question is artificial and different from what people within that context would ask). Several studies show that students are more motivated by authentic questions than by authentic contexts. Embedding these findings, I discuss issues associated with defining authenticity in education. A first issue is that philosophers use the term to characterize a person’s existential …
Virtual and Augmented Reality Applied to the Perception of the Sound and Visual Garden
2022
The COVID-19 situation has encouraged the creation of ICT-based learning environments. Difficulties in performing activities in a garden setting can be overcome by using Virtual Reality (VR) and Augmented Reality (AR). The aim of this research is to evaluate the usefulness of VR and AR as an educational resource through contextualised sensory experiences in the garden. Eighty-seven trainee teachers took part, and a mixed methodology was used, for the analysis of the sound and visual elements of the garden and for reflection on the usefulness of VR and AR. An interpretive and inferential analysis of the AR-based compositions was carried out and of the drawings of the garden created by the pa…
Teacher Agency and Futures Thinking
2022
Problems encountered in top-down school reforms have repeatedly highlighted the significance of teachers’ agency in educational change. At the same time, temporality has been identified as a key element in teachers’ agency, with teachers’ beliefs about the future and experiences of the past shaping their agentic orientations. However, research on teachers’ future orientations is typically limited to short-term trajectories, as opposed to long-term visions of education. To address this, we draw on a futures studies perspective to give more explicit attention to teachers’ long-term visions of their work. We argue that the method of future narratives, already well…
Blending canal surfaces along given circles using Dupin cyclides
2013
We study blends between canal surfaces using Dupin cyclides via the space of spheres. We have already studied the particular case where it is possible to blend two canal surfaces using one piece of Dupin cyclide bounded by two characteristic circles, but this is not possible in the general case. That is why we solve this problem using two pieces of different cyclides, which is always possible. To get this conclusion and give the algorithms allowing to obtain such a result, we study, at first, the blend between two circles by a piece of cyclide. We impose to the cyclide to be tangent to a given sphere containing one of the circles. We give the existence condition on the previous circles to h…
Iterative construction of Dupin cyclides characteristic circles using non-stationary Iterated Function Systems (IFS)
2012
International audience; A Dupin cyclide can be defined, in two different ways, as the envelope of an one-parameter family of oriented spheres. Each family of spheres can be seen as a conic in the space of spheres. In this paper, we propose an algorithm to compute a characteristic circle of a Dupin cyclide from a point and the tangent at this point in the space of spheres. Then, we propose iterative algorithms (in the space of spheres) to compute (in 3D space) some characteristic circles of a Dupin cyclide which blends two particular canal surfaces. As a singular point of a Dupin cyclide is a point at infinity in the space of spheres, we use the massic points defined by J.C. Fiorot. As we su…
Round-handle decomposition ofS2×S1
2007
A round-handle decomposition is associated with a non-singular Morse–Smale flow on 3-manifolds prime to S 2× S 1. This decomposition has been built only for the 3-sphere S 3. In this paper we obtain the round-handle decomposition of non-singular Morse–Smale flows on S 2× S 1, in order to get all the different fattened round handles in this manifold. Some of them include non-separating boundary components that induce the topology of the links of periodic orbits.

2008
The necessary and sufficient conditions are extracted for periodicity of bi-ideals. They cover infinitely and finitely generated bi-ideals.
